产品概述

The MCP3903-E/SS is a 6-channel Delta Sigma A/D Converter with analogue front end (AFE) contains three pairs made out of two synchronous sampling delta-sigma analogue-to-digital converters (ADC) with PGA, a phase delay compensation block, internal voltage reference and high-speed 10MHz SPI compatible serial interface. The converters contain a proprietary dithering algorithm for reduced idle tones and improved THD. The internal register map contains 24-bit wide ADC data words, a modulator output register as well as six 24-bit writable control registers to program gain, over-sampling ratio, phase, resolution, dithering, shut-down, reset and several communication features. The communication is largely simplified with various continuous read modes that can be accessed by the direct memory access (DMA) of an microcontroller and with separate data ready pins that can directly be connected to the interrupt request (IRQ) input of an MCU.
  • 91dB SINAD
  • -100dBc Total harmonic distortion (THD) (up to 35th harmonic)
  • 102dB Spurious-free dynamic range (SFDR) for each channel
  • Programmable data rate up to 64kSPS
  • Ultra low-power shutdown mode with <2µA
  • -115dB Crosstalk between any two channels
  • 5ppm/°C Low drift internal voltage reference
  • Differential voltage reference input pins
  • High gain PGA on each channel (up to 32V/V)
  • Phase delay compensation between each pair of channels with 1µs time resolution
  • High-speed addressable, 10MHz SPI interface with mode 0,0 and 1,1 compatibility
  • Independent analogue and digital power supplies
